#PutMapping("/infoUtile/update/{id}")
public Map<String,Object> editActualite(#PathVariable Long id, #Valid #RequestParam ArrayList<Long> idDeleted,
#Valid #RequestParam String content, #Valid #RequestParam String description){
InformationUtile info = this.infoUtileService.getInfoUtileById(id);
info.setContent(content);
info.setDescription(description);
info.setDate(new Date());
if(idDeleted.size() != 0) {
for (int i = 0; i < idDeleted.size(); i++) {
this.mediaService.deleteMedia(idDeleted.get(i));
}
}
InformationUtile i = this.infoUtileService.addOrEditInfoUtile(info);
return getInfoUtileWeb(i);
}
and here is my test that Im trying to implement
#Test
public void update() throws Exception {
InformationUtile informationUtile = new InformationUtile();
informationUtile.setId(1);
informationUtile.setContent("oumaima");
informationUtile.setDescription("test");
Media medias = new Media();
medias.setId(1);
medias.setType("image/png");
medias.setUrl("C:\\files\\actualite\\32769\\adobexd.png");
List<Media> allMedias = new ArrayList<Media>();
allMedias.add(medias);
informationUtile.setMedias(allMedias);
User user = new User();
user.setId(1);
user.setNom("oumaima");
informationUtile.setUser(user);
ArrayList<Long> idDeleted = new ArrayList<>();
idDeleted.add(0L);
Mockito.when(informationUtileService.getInfoUtileById(Mockito.<Long>any())).thenReturn(new InformationUtile());
Mockito.when(informationUtileService.addOrEditInfoUtile(Mockito.any(InformationUtile .class))).thenReturn(informationUtile);
mockMvc.perform(put("/infoUtile/update/{id}",informationUtile.getId()).requestAttr("idDeleted",idDeleted)
.param("content",informationUtile.getContent())
.param("description",informationUtile.getDescription())
)
.andExpect(status().isOk());
verify(informationUtileService, times(1)).getInfoUtileById(informationUtile.getId());
verify(informationUtileService, times(1)).addOrEditInfoUtile(informationUtile);
verifyNoMoreInteractions(informationUtileService);
}

Answer 1

You are defining three request parameters at your endpoint #Valid #RequestParam ArrayList<Long> idDeleted, #Valid #RequestParam String content, #Valid #RequestParam String description which means they are query parameters after the url, e.g. http://localhost:8080/?idDeleted=1&idDeleted=2&content=Hello&description=Duke.
The HTTP 404 indicates that Spring could not find a handler for your request, meaning the client (in your case MockMvc) has a malformed URL.
In your current MockMvc request setup you are using .requestAttr() for the idDeleted request parameter.
All of them should be .param():
mockMvc
.perform(put("/infoUtile/update/{id}",informationUtile.getId())
.param("idDeleted", idDeletedOne , idDeletedTwo)
.param("content",informationUtile.getContent())
.param("description",informationUtile.getDescription())
)
PS: I guess the #Valid annotations are redundant/not needed here as you are not checking e.g. payload which has Bean Validation annotations to verify the content.
UPDATE: .param() is overloaded with .parm(String name, String... values), so you can pass your list of idDeleted with either .param("idDeleted", idDeletedOne, idDeletedTwo) or you can pass a String[] with all your Long values represented as a String
